At home, my main workstation is a 400Mhz AMD K6 running Debian (currently woody, but I can
also boot into sid if I’m feeling daring). It also has FreeBSD, OpenBSD and an old unloved version
of Debian GNU/Hurd
installed.

We’ve also got a server running Debian (woody/stable), an Gateway
Pentium Pro 200 MHz, which handles our email, databases and web
developement, and other useful services like DNS and DHCP.
